Quick Answer
Okay, so here's the quick version. Keeping your house pest-free isn't a one-and-done deal; it's a four-seasons job. Most of the time, the problem's simple: your house has got holes, and you're leaving a free buffet out. You gotta seal up every crack you can find and get militant about crumbs and trash. A little caulk and some good cleaning habits will solve 80% of your problems before they ever start. You can do most of this yourself for under $50, but a recurring issue might mean calling a pro for a few hundred bucks.
Common Symptoms
Possible Causes
Step-by-Step Diagnosis
Step 1
Walk the entire perimeter of your house. Look for any crack or hole in the foundation, siding, and around utility lines. Check if you can see daylight under doors.
Step 2
Inspect the exterior for overgrown vegetation. Trim any tree branches or shrubs that are touching the house, as these act as bridges for pests.
Step 3
Go inside and thoroughly inspect the kitchen and bathrooms. Use a flashlight to check under sinks, behind the refrigerator, and behind the toilet.
Step 4
Check dark, undisturbed areas like the attic, basement, crawl space, and garage. Look for droppings, nests, and chew marks.
Step 5
If you're unsure of the pest, place sticky traps along walls in areas where you suspect activity. This will help you identify what you're up against.
Step 6
Be honest about your food storage. Check if all pantry items, including pet food, are in airtight containers and that crumbs and spills are cleaned up promptly.

When to Call a Professional Pest Control
- If you see any signs of termites (mud tubes, discarded wings) or bed bugs (bites, spots on mattresses). Do not try to treat these yourself. Ever.
- When you have a recurring problem despite sealing entry points and cleaning up. It means the pests have found a way in that you can't see.
- If you find evidence of rats or wildlife like raccoons or squirrels. These animals can cause significant damage and carry diseases.
- When you're facing a large-scale infestation, like seeing multiple cockroaches every time you turn on a light. You're past the point of DIY traps.
- If you're not comfortable handling pesticides or you can't physically do the inspection and exclusion work in attics or crawl spaces.
Prevention Tips
- Do a full exterior inspection every spring and fall to find and seal any potential entry points with caulk or steel wool.
- Store all food, including pet food, in hard plastic or glass airtight containers. Never leave food in just a bag or cardboard box.
- Fix any water leaks immediately. Ensure your basement or crawl space is dry, using a dehumidifier if necessary.
- Keep all vegetation, including shrubs and tree limbs, trimmed at least one foot away from your house's siding and roof.
- Reduce clutter in your attic, garage, and basement. Store items in sealed plastic totes, not cardboard boxes.
- Keep your outdoor trash cans sealed tightly and store them away from the house if possible.
- Don't let dirty dishes pile up in the sink, and wipe up all crumbs and spills from counters and floors right away.
